About 7 weeks ago I noticed 2 snails in my aquarium, which I guess must have come from a plant, and I got rid of them, but I guess there were more. I left for camp after that so I had no control. My fish were taken care of, but not the snails. I got back yesterday, and today I did a nice water change, and took out at least 30 snails, but I know I have more. I want to get rid of ALL of them before they multiply again, but I don't want to use a chemical that could harm my fish unless it's a must. I tried putting in some lettuce and cucumber, by none of the snails went to it. What do I do? How should I get rid of them?
Thanks a lot.
